[英]How to rotate a subplot in matplotlib freely
我目前正在编写一个程序,可以在我的计算机屏幕上投影全息视频,我编写了下面的代码,但我不知道如何专门旋转子图,我创建了一个 3*3 子图,我需要旋转子图4 x 270 顺时针,子图 6 x 90 顺时针和子图 8 x 180。
第二个问题是如何去掉所有的轴 label... 这样投影出来的全息图会很好很整齐....
import pandas as pd
import serial
import numpy as np
import matplotlib.pyplot as plt
ser = serial.Serial("COM5", 115200) # define the serial port that we are communicating to and also the baud rate
plt.style.use('dark_background') #define the black background
plt.ion() # tell pyplot we need live data
fig,[[ax1,ax2,ax3],[ax4,ax5,ax6],[ax7,ax8,ax9]] = plt.subplots(3,3) # plotting a figure with 9 subplot
Xplot = []
Yplot = []
Zplot = []
blankx = []
blanky = []
fig = [ax1,ax2,ax3,ax4,ax5,ax6,ax7,ax8,ax9]
while True: #always looping this sequence
while(ser.inWaiting()==0): #if no input from the serial, wait and do nothing
pass
data = ser.readline() #obtain the input from COM 5
data_processed = data.decode('utf-8') #to get rid of the unnecessary string part
data_split = data_processed.split(",") # split the incoming string into a list
x = float(data_split[0]) #to obtain seperate float values for x,y,z
y = float(data_split[1])
z = float(data_split[2])
reset = int(data_split[3]) # reset will output 1
draw = int(data_split[4]) # draw will output 2
if(draw == 2):
Xplot.append(x) #if draw is given instruction, add the x,y,z value into the list to be plot on the graph
Yplot.append(y)
Zplot.append(z)
ax1.plot(blankx,blanky) # subplotting
ax2.plot(Xplot,Yplot,"ro")
ax3.plot(blankx,blank)
ax4.plot(Xplot,Yplot,"ro")
ax5.plot(blankx,blank)
ax6.plot(Xplot,Yplot,"ro")
ax7.plot(blankx,blanky)
ax8.plot(Xplot,Yplot,"ro")
ax9.plot(blankx,blanky)
if(reset == 1):
for f in fig: #if reset is given instruction, clear all figure and clear the elements in the plotting list
f.clear()
Xplot = []
Yplot = []
Zplot = []
plt.pause(.000001)
我可能已经找到了一个解决方案,但不是一个完美的解决方案,我使用数学而不是代码来旋转绘图,只需将其乘以负值以在 x 和 y 轴上翻转,我还添加了降噪器 function 以降低偏差,这是我使用的代码,如果有人对如何自由旋转子图有任何想法,请启发我。
